About This PhD Project

Project Description

This group participates in the Wellcome Trust 4 year PhD programme in Developmental biology., MRC and BBSRC Doctoral Training Programmes.

Common inflammatory diseases such as rheumatoid arthritis and sepsis are caused by the abnormal activation of pattern recognition receptors, proteins that recognise pathogen associated molecules such as bacterial lipopolysaccharide. Ng’s lab studies the molecular mechanism of of signalling by PRRs focussing on the Toll - like receptors (see Gay et Nature Rev Immunol, 14, 546.

Methods. Protein expression in bacteria and culture cells. Purificaion using FPLC, affinity chromatography and allied techniques. Crystallographic screening. X-ray crystallography. CryoEM, Super resolution microscopy,

Other projects available (1) Regulation of inflammatory signalling by BCAP and PI3 kinase (2) Role of LRRK2 in the development of Parkinson’s disease (3) Molecular basis of viral haemorrhagic fever and sepsis (4) Insect Toll receptors in immunity, nervous system and pathogen homeostasis in disease vectors such as mosquito.
